Question about V2.0.1

Hey

Can you guys tell me what the major differences from V2.0.1 to V2.0.2?
Obviously they where very different cause V2.0.1 came out with some torque values at 100% and race fuel wasnt needed?

Thanks

v2.0.2 is a better map. It is smoother and makes more top end power. And it is scaled so that users can adust the User Tq value as per the documentation. v2.0.1 isn't as friendly when it comes to make User Tq changes since it doesn't have the same value across the board.

Thanks shiv

Last question

Im getting the a little more boost with V201 on pump fuel than v202 on 94% with high octane.
Does that mean im getting roughly the same power and torque?

Hard question to answer given that boost is only one contributor to power output. Typically, after a certain boost level, running race gas will give you more power than an extra pound of boost.
